Sažetak
Biodrying is an aerobic process during which the moisture content of waste is reduced while the degradation of organic waste is kept to a minimum. The main purpose of the biodrying process, as opposed to the composting process, is not to maximize the degradation of organic material, but to bring about the biodegradation of organic waste to an extent sufficient to produce biologically induced heat to dry the waste via evaporation. The present research was an attempt to numerically model an aerobic bio- oxidation (biodrying) process based on relevant experimental data published in the literature. Moisture content removal and generation of carbon dioxide and ammonia during the biodrying process were examined. Furthermore, the potential of the biodrying process to produce a high quality refuse-derived fuel (RDF) product is discussed. Given its simplicity, the numerical model used in this study did not take into account many important aspects of the biodrying process. However, its usefulness as a first approximation of the real biodrying process, was confirmed.
